RC7106
PRODUCT SPECIFICATION
10
Notes:
1. RC7106 logic inputs have internal pull-up resistors.
2. All clock outputs loaded with maximum lump capacitance
test load specified in AC Electrical Characteristics section.
3. X1 input threshold voltage (typical) is VDD/2
4. The RC7106 contains an internal crystal load capacitor be-
tween X1 and VSS and another between X2 and VSS.
The total load placed on the crystal is 18pF; this includes
typical stray capacitance of short PCB traces to the crystal.
5. X1 input capacitance is applicable when X1 is driven with
an external clock source (X2 is left unconnected).
